Provision IGs in EKS directly with AWS SDK about instance-manager

[eytan-avisror]

minion-manager should support providing recommendation so that it is compatible with eks-cf provisioner - the work has already been done on the recommendation reconciler here #36 .

You are talking about making changes to a reconciling object from other components - this will always be a problem if you go around the controller.

Even when using SDK to create resources, if a different component changes something under the controller then the next reconcile will try to take it back to whatever the CR is declaring as the desired state.

Regardless of that, we should have an eks-sdk provisioner - this however would require significant amount of work and is a matter of prioritizing.

Agreed that minion-manager could implement the events based approach and get the desired result. But what about cases where tags on the ASGs need to be updated at run time (new tags added, old tags removed, etc.). One use-case for that is to enable/disable cluster-autoscaler.

[eytan-avisror]

Tags are not overwritten by reconcile, only Cloudformation objects (tags are part of the API call, not the template)

Outside of that - cloudformation will not strip manually added tags according to what we tested
